Učinki različnih načinov redčenja v gorskem bukovem gozdu na Mežakli : diplomsko delo = univerzitetni študij = Effects of different thinning regimes in mountain beech forest on Mežakla : graduation thesis - university studiesLaznik, Luka, 1986-V letu 2009 je bila izvedena druga meritev na raziskovalnih ploskvah v bukovihdrogovnjakih na Mežakli, ki so bile postavljene in prvič premerjene v letu 2005. Uporabljeni so bili trije načini ... ukrepanj. Prvi je bil način klasičnega izbiralnega redčenja z običajno jakostjo odkazila (način 60), drugiredčenje s 50 % manjšo gostoto izbrancev z običajno jakostjo odkazila (način 30), tretji pa redčenje s 75 % manjšo gostoto in močno jakostjo odkazila (način dela 15). Izbrancem je bila določena drevesna vrsta, izmerjen premer, višina, dolžina čistega debla, preštete veje na prvih in drugih 4 m debla, določena asimetričnost krošenj ter sproščenost. Po štirih vegetacijskihsezonah so opazne manjše razlike med načini dela, vendar je potrebno upoštevati, da so rezultati predhodni. Način 15 se je izkazal kot ugoden, če želimo povečati premer debla izbrancev in volumen krošenj ter zagotoviti boljšo stojnost. Način 30 se je izkazal najboljše pri čistem deblu in številu tankih vej na prvih 4 m debla. V kolikor želimo boljše čiščenje debelih vej ali pa izboljšanje sproščenosti, se bomo odločili za način dela 60. Če pa sestoje prepustimo naravnemu razvoju, bo to najboljše vplivalo na višinsko rast in majhno število tankih vejic. Način dela 15 zaradi močnega ukrepanja odmakne naslednje ukrepanje v prihodnost. Z načinom dela 30 lahko zmanjšamo razmerje h/d in povečamo krošnje, kar je na področju s pogostimi ujmami zelo pomembno. Tudi način dela 60, ki predstavlja klasično izbiralno redčenje in je v dosedanji praksi najpogostejše v uporabi, daje dobre rezultate in ne predstavlja bistveno večjih vložkov, kot jih zahtevajo drugi načini redčenj, ki smo jih preizkušali.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [L.
